Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a grassland soil loosening and reseeding machine. BACKGROUND

[0002] Replanting and soil loosening in grassland are important measures to maintain the health of grassland ecosystems and improve the yield of forage grasses. Replanting can increase plant diversity in grasslands, replenish aging or damaged forage resources, while soil loosening can improve soil structure, promote water and nutrient absorption, and create a better environment for forage grass growth. These measures, working together, not only improve the quality and yield of forage grasses, but also enhance the self-repairing ability of grasslands, reduce soil erosion, and thus achieve sustainable use of grassland resources.

[0003] In the prior art, such as the grassland root cutting and soil loosening fertilizer machine disclosed in patent CN 213029137 U, a cutting cutter and a soil loosening shovel are arranged in front and back layout. In this structure, the cutting cutter not only cuts off the grass roots but also cuts open the soil. If the soil is relatively solid, the cutting difficulty is large, and the soil loosening shovel is placed at a far position behind the cutting cutter, which also has the problem of large forward resistance. SUMMARY

[0004] The purpose of the present application is to overcome the deficiencies in the prior art and provide a grassland soil loosening and reseeding machine that can effectively reduce the difficulty of breaking soil and cutting roots and improve the soil loosening effect.

[0005] Technical solution: To achieve the above purpose, the grassland soil loosening and reseeding machine of the present application comprises a frame, the frame has support wheels on both sides, a plurality of soil loosening and seeding mechanisms are installed between the two support wheels, and a seed box is installed on the frame above all the soil loosening and seeding mechanisms.

[0006] The soil loosening and seeding mechanism comprises a mechanism seat body, a soil loosening shovel, a cutting disc, and a seed throwing mechanism. The soil loosening shovel comprises a shovel handle and a shovel tip.

[0007] The shovel handle can rotate relative to the mechanism seat body, so that the soil loosening shovel can be switched between the working state and the lifted state. In the working state, the shovel handle is wrapped from the rear side of the cutting disc to the lower side of the cutting disc, so that the shovel tip is located in front of the cutting disc.

[0008] With the above structure, on the one hand, the cutting disc cuts the grass root soil along the way in front, reduces the walking resistance of the shovel handle, so that the soil loosening shovel can reach a deeper position to implement the soil loosening work; on the other hand, since the shovel tip is in front of the cutting disc, the shovel tip can pry the soil at a deeper position, break the soil and move forward, so that cracks are formed in the soil around the shovel tip, achieving good soil loosening effect, the soil above the shovel tip is loosened, and the grass roots are straightened, facilitating the cutting disc to cut the grass roots, and reducing the resistance of the soil to the cutting disc.

[0009] In the initial state, the soil loosening shovel is in the raised state, when the machine starts to work, the frame first moves forward for a distance, so that the cutting disc first cuts a slit on the ground, and then the soil loosening shovel is controlled to switch to the working state, and the shovel tip moves along the slit until it is in place. When the machine needs to turn or stop working, the soil loosening shovel is controlled to switch to the raised state.

[0010] Preferably, a groove is arranged on the shovel handle for the rear edge of the cutting disc to be embedded, so that the shovel handle can support the cutting disc and prevent the cutting disc from swinging.

[0011] Further, the shovel tip can be regularly twisted relative to the shovel handle.

[0012] Further, the rear end of the shovel tip is fixed with a shaft body; the end of the shovel handle has a mounting hole, the hole wall of the mounting hole has a guide sliding groove; a sliding piece is mounted on the inner side of the mounting hole, the sliding piece has a placement part placed in the guide sliding groove, and a spring is arranged between the hole bottom of the mounting hole and the sliding piece; the shaft body is rotationally mounted relative to the shovel handle, and the shaft body has a spiral part, and the sliding piece has a part matched with the spiral part; the shovel handle has a steel wire rope connected with the sliding piece; and a pulling mechanism connected with the steel wire rope is mounted on the shovel handle.

[0013] Further, the pulling mechanism includes a motor mounted on the shovel handle, and the output shaft of the motor has an eccentric wheel; the pulling mechanism further includes a pulling piece slidingly mounted relative to the shovel handle, and the pulling piece has a square hole part for the eccentric wheel to be placed in. When the motor rotates, the eccentric wheel makes the pulling piece reciprocatingly slide relative to the shovel handle, the pulling piece retracts and releases the sliding piece through the steel wire rope, the steel wire rope and the spring comprehensively act on the sliding piece to make the sliding piece reciprocatingly slide, and the sliding piece makes the shaft body reciprocatingly swing through the matching action of the spiral part, so that the shovel tip can reciprocatingly swing relative to the shovel handle.

[0014] Further, the shaft body has a part matched with the mouth of the mounting hole as a rotary pair, and a pin shaft is mounted on the shaft body, the shovel handle has a strip-shaped hole extending along the circumference of the mounting hole, and the end of the pin shaft is placed in the strip-shaped hole. The pin shaft can prevent the shaft body from moving axially relative to the shovel handle, and does not affect the rotation of the shaft body, and the connection is reliable.

[0015] Further, a cover plate covering the strip-shaped hole is mounted on the outer side of the shovel handle, and the cover plate can prevent soil from entering the strip-shaped hole.

[0016] Further, the front side of the cutting disc has a grass separating piece, which has a structure of being sharp in front and wide in back, and the back side of the grass separating piece surrounds the front side of the cutting disc.

[0017] Further, an oil cylinder is connected between the shovel handle and the mechanism seat body.

[0018] Beneficial effects: The grassland soil loosening and reseeding machine has the following beneficial effects:

[0019] (1) The soil loosening shovel and the cutting disc assist each other, the shovel handle of the soil loosening shovel is not blocked by grass roots, the shovel tip acts on a deeper position where there are fewer grass roots, and the shovel tip can loosen the soil in front of the position where the cutting disc is about to act, thereby reducing the difficulty of breaking the soil by the cutting disc, and making the cutting disc more easily cut off the grass roots.

[0020] (2) The shovel tip can more effectively pry the soil through active movement, so that the soil can spread more cracks from a deeper position, and even make the soil along the way bulge, thereby producing a better soil loosening effect and improving air permeability.

[0021] (3) The structure for driving the regular torsional movement of the shovel tip is compact, and can effectively drive the shovel tip to swing back and forth in the soil.

[0022] (4) The grass separating piece can separate the grass clumps, so that the cutting disc does not harm the pasture on the ground, and the grassland soil loosening and reseeding machine does not damage the original pasture while reseeding the pasture. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 1 The grassland loosening and reseeding machine shown includes a frame 1, with support wheels 2 on both sides of the frame 1, and multiple loosening and sowing mechanisms 3 installed between the two support wheels; a seed box 4 is also installed on the frame 1 above all the loosening and sowing mechanisms 3.

[0035] like Figures 2 to 5 As shown, the soil loosening and sowing mechanism 3 includes a mechanism base 34, a soil loosening shovel 31, a cutting disc 32, and a seeding mechanism 33; the soil loosening shovel 31 includes a shovel handle 31a and a shovel tip 31b; the shovel handle 31a can rotate relative to the mechanism base 34, so that the soil loosening shovel 31 can switch between the working state and the lifting state. Specifically, a hydraulic cylinder 350 is connected between the shovel handle 31a and the mechanism base 34.

[0036] In operation, the shovel handle 31a moves from the rear side of the cutting disc 32 to the lower side of the cutting disc 32, so that the shovel tip 31b is located in front of the cutting disc 32.

[0037] With the above structure, on the one hand, the cutting disc 32 cuts the grass root soil in front, reduces the walking resistance of the shovel handle 31a, so that the soil loosening shovel 31 can reach a deeper position to implement the soil loosening work; on the other hand, since the shovel tip 31b is in front of the cutting disc 32, the shovel tip 31b can pry the soil at a deeper position, break the soil and advance, so that the soil forms cracks around the shovel tip 31b, achieving good soil loosening effect, the soil above the shovel tip 31b is loosened, and the grass roots are straightened, facilitating the cutting disc 32 to cut the grass roots, reducing the resistance of the soil to the cutting disc 32. In this way, the soil loosening shovel 31 and the cutting disc 32 assist each other, the shovel handle 31a of the soil loosening shovel 31 is not blocked by the grass roots, the shovel tip 31b acts on a deeper position with less grass roots, and the shovel tip 31b can pre-loosen the soil before the position where the cutting disc 32 will act, reducing the difficulty of breaking the soil of the cutting disc 32, and making the cutting disc 32 easier to cut off the grass roots.

[0038] In the initial state, the soil loosening shovel 31 is in the lifted state, when the machine starts to work, the machine frame 1 first moves forward for a distance, so that the cutting disc 32 first cuts a slit on the ground, and then the soil loosening shovel 31 is controlled to switch to the working state, and the shovel tip 31b moves along the slit until it is in place. When the machine needs to turn or stop working, the soil loosening shovel 31 is controlled to switch to the lifted state.

[0039] A groove d is provided on the shovel handle 31a for the rear edge of the cutting disc 32 to be embedded, so that the shovel handle 31a can support the cutting disc 32 to prevent it from swinging.

[0040] Preferably, the shovel tip 31b can be regularly twisted relative to the shovel handle 31a. In this way, the shovel tip 31b can pry the soil more effectively through active movement, so that the soil can spread more cracks from a deeper position, even causing the soil along the way to bulge, achieving better soil loosening effect and improving air permeability. Figure 6 As shown, the rear end of the shovel tip 31b is fixed with a shaft body 35; as shown, Figure 6 As shown, the end of the shovel handle 31a has a mounting hole a, the hole wall of the mounting hole a has a guide sliding groove b; a sliding piece 36 is mounted on the inner side of the mounting hole a, the sliding piece 36 has a placement part placed in the guide sliding groove b, and a spring 37 is arranged between the hole bottom of the mounting hole a and the sliding piece 36; the shaft body 35 is rotationally mounted relative to the shovel handle 31a, and the shaft body 35 has a spiral part, and the sliding piece 36 has a part matched with the spiral part; the shovel handle 31a has a steel wire rope 38 connected with the sliding piece 36; the shovel handle 31a is mounted with a pulling mechanism connected with the steel wire rope 38.

[0041] Specifically, as shown, Figure 9As shown, the pulling mechanism includes a motor 39 mounted on the shovel handle 31a, and the output shaft of the motor 39 has an eccentric wheel 310; the pulling mechanism further includes a pulling piece 320 slidingly mounted relative to the shovel handle 31a, and the pulling piece 320 has a square hole portion for the eccentric wheel 310. When the motor 39 rotates, the eccentric wheel 310 makes the pulling piece 320 reciprocally slide relative to the shovel handle 31a, and the pulling piece 320 retracts and releases the sliding piece 36 through the steel wire rope 38, and the steel wire rope 38 and the spring 37 together make the sliding piece 36 reciprocally slide, and the sliding piece 36 reciprocally swings the shaft body 35 through the cooperation of the screw portion, thus the shovel tip 31b can reciprocally swing relative to the shovel handle 31a. The structure for driving the shovel tip 31b to swing regularly is compact, and can effectively drive the shovel tip 31b to reciprocally swing in the soil.

[0042] As shown in Figure 8 The shaft body 35 has a portion in rotational pair cooperation with the mouth of the mounting hole a, and the shaft body 35 is mounted with a pin shaft 330, and the shovel handle 31a has a strip-shaped hole c extending along the circumference of the mounting hole a, and the end of the pin shaft 330 is placed in the strip-shaped hole c. The pin shaft 330 can prevent the shaft body 35 from axially moving relative to the shovel handle 31a, and does not affect the rotation of the shaft body 35, and the connection is reliable. The outer side of the shovel handle 31a is mounted with a cover plate 340 covering the strip-shaped hole c, and the cover plate 340 can prevent the soil from entering the strip-shaped hole c.

[0043] The front side of the cutting disc 32 has a grass separating piece 5, which is a structure of front sharp and rear wide, and the rear side of the grass separating piece 5 surrounds the front side of the cutting disc 32. The grass separating piece 5 can separate the grass clumps, so that the cutting disc 32 does not harm the pasture on the ground, and the grassland loosening and reseeding machine does not damage the original pasture while reseeding the pasture.
